4.4.4.
DC power output
The Impact Controller (including all devices powered by the controller via network ports) is powered only
via DC power input from DCA2.500 DC output.
AUX DC OUT has a built-in current limit, maximum load is 60W (2A @30V).
Connect “AUX DC OUT” of the DCA2.500 to the “24V DC POWER” input of the Controller.
Check the polarity!
4.4.5.
AMP LINK
Connect the AMP LINK between the Controller and DCA2.500 amplifiers.
The AMP LINK (RED vertical connection cat5 cable) is the secured bus
connecting the Impact Controller with up to 32 x DCA2.500 amplifiers.
Based on RS485, this internal system bus provides:
-
2 balanced audio channels across the entire AMP LINK chain,
monitored;
-
Control and diagnostics data interface.
AMP LINK provides daisy-chain bus in two modes:
a)
To the IMPACT Controller, when the DCA2.500 is a part of the
IMPACT system (all Impact amplifiers daisy-chained to the
Controller).
b)
To other DCA2.500 amplifiers, without an Impact Controller, when
the DCA2.500 belongs (with one or more other DCA2.500 units)
to a
charging cluster
and shares the same battery pack (see chapter “Cluster charging”) with the
group: in this case the amplifier and the entire charging cluster is able to work without IMPACT
Controller
NOTE:
The DCA2.500 can also work as a standalone unit without any AMP LINK connected.
NOTE: On customers request, DCA2.500 amplifier can be equipped with optional DUAL AUX input module.
More information about DUAL AUX input module available at 4EVAC on request.
In an Impact system, connect the amplifiers to the AMP LINK into a daisy chain, starting from the Controller.
Amplifiers will be addressed and managed by the Controller according to the connection order, i.e. the first
amplifier connected directly to the Controller receives the address of Amp 1, next the address of Amp 2,
etc.
